Arduino Leonardo Controller Button Issue on Recalbox with Raspberry Pi 4B
ChrisHaruki opened this issue · comments
Hello everyone!
I'm in need of some assistance with a custom Arduino Leonardo game controller I've been working on. I've utilized the library here to set up my controller. It's functioning perfectly when tested on the Windows gamepad settings—every button press and joystick movement is detected without any hiccups.
However, I've hit a snag with Recalbox on my Raspberry Pi 4B. While the system does recognize the controller as a Leonardo and allows me to use the joystick to navigate the Recalbox menu, none of the buttons are being detected within the controller configuration menu.
Has anyone experienced a similar issue, or can offer any insights into why this might be happening? Your help would be immensely appreciated to get my custom controller fully operational with Recalbox.
Thank you in advance!
Here is my arduino code:
`/*
Select: button8
Start: button9
Hotkey: button9
L: button4 (Joystick L button)
R: button5 (Joystick R button)
X: button0
Y: button3

D-U: axis 1-
